TANK FOR LIQUIDS.

To all whom it may concern.'

Be it known that I, PERRY Onur, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Tanks for Liquids, of which the following is a specilicat-ion.

This invention relates to tanks for liquids and has for its object the provision of a pair of valves for controlling the flow of the liq uid from the tank and for permitting the ingress of air at the top of the tank. A tank of this character may be utilized in many places; forinstance noon automobiles it provides etlicient means for cutting olf the gasolene from the tank to the carbureter, eliminating the danger of leakage and convides a safe and efficient method of storing gasolene for lighting purposes upon trains, the valves in the tank being electrically controlled in such manner that if the electrical connections are broken by the shock of a collision or otherwise, the valves are automatically closed to prevent the passage of the gasolene therefrom. These and many other applications of the device will readily suggest themselves to persons desiring vto employ tanks of this character.

Further objects and advantages of the invention will be set forth in the detailed description which now follows.

The ligure shown in theaccompanying drawing, is a vertical sectional view of a. tank constructed in accordance with the in- I vention with the electrical wiring diagrammatically illustrated.

Referring to the drawing, the numeral 5 designates a tank haivng an ening 6 in the top thereof andan opening in the bot tom thereof. A filling sleeve 8 is adapted to be closed by a plug 9. The valves at the top and bottom of the tank are eXactl alike and a description of one will sutce or both of them. These valves comprise magnets 10 and 11, the cores 12 and 13 of which are of substantl y inverted U-form, Said cores having nturned ends 14 and' 15.. The ma net win ings are indicated at 16 andl, these windings being in series with each other and with a source of electrical energy indicated at 18, through the medium of conductors 19 and 20. A switch 21 provides means for closing the circuit when desired, to open the valves.

Serial No. 544,192.

Cross bars 22 and 23 are secured to the cores 12 and 13 by screws 24, and 25. Springs 26 and 27 bear between these bars and the armatures 28 and 29. Valves 30 and 31 are provided with stems 32 and 33, `said stems being slidably disposed in sleeve eX- tensions 34 and 35 of the bars22 and 23. The armatures 28 and 29 engage the valves 3() and 31 and normally tend to close said valves under the influence of the springs 26 and 27, so that if for any reason current is not present in the circuit to energize the cores 12 and 13, the springs'26 and 27 act to vclosing of the valve 30 preventing the passage of air to the interior of the tank through the port 37. 1t will therefore be seen that the present invention comprises -simple and eflicient means for controlling the air inlet valve and the fluid outlet valvel without theuse of any moving parts extending from the' out-side to the inside of the tank, whereby the necessity of the employ viated. It will also be seen that while the control of the valves is entirely electrical, the windings for the controlling magnets, are located upon the exterior of the tank, said windings being electrically connected in'such manner that the valves are operated in unison. V i

It is apparent that if a tank of this character is used upon an automobile and the current for energizing the magnets, is secured from the magneto usually employed upon automobiles, the stopping of the automobile engine will automatically out olf the flow of gasolene to the carbureter, whereby the loss and danger from lire, resulting from leaking earbureters is eliminated.

It is often desired to employ fluid fuel for the lighting of trains and the herein described tank is particularly adapted for use `in this connection. No Huid can pass from the tank to the points where it is to be used until the electrical circuit is manually closed by the switch 21 and if by reason of collision or other accident, Vthis electrical circuit is breken, the flow of Huid from the tank is at once stopped and the danger o f setting lire to the train is greatly minimized.

From the foregoing description, it will be seen that simple and efficient mea-ns are here- Vment of any stuiling boxes or glands, is ob in provided for accom lishing the objects of the invention, but Whi e the elements shown and described are Well adapted to serve the purposes for which they are intended, itis to be -understood that the invention is not limitedto the precise construction set forth, `but includes Within its purview such changes as may be made Within the scope of the appended claim.

What I claim, isv The combination With a fluid fuel tank having an opening in the top and bottom thereof, of a magnet core projecting through the top of the tank and a magnet core L projecting through the bottom of the tank,

windings for said cores located upon the eX- terior of the tank, an electric circuit in Which sald windings are included, a source of electrical energy in said circuit, an air inlet controllin valve located upon the interior of the tan a spring normally tending to close said valve, an armature arranged to be' attracted by the magnet core at the top of the tank, said armature when attracted by Vsaid magnet core opening the air inlet valve, an armature arranged to be attracted by a magnet core at the bottom of the tank, said armature When attracted serving to open the fluid outlet valve, and springs normally tending to close said valves.

In testimony whereof I affix my signature in presence of tWo- Witnesses. v
